Résumé

The paper presents a systematic numerical study on a two-dimensional, steady-state and laminar natural convection in a rectangular enclosure with discrete heat sources on walls. A new combined temperature scale is suggested to non-dimensionalize the governing equations of natural convection induced by multiple temperature differences. It is valuable to simplify the coupled boundary conditions and to identify the relative strength of the heat source. The heat and fluid flow structures are fully examined using streamlines and heatlines.
